Hello @sergio,

Could you provide me with the following information:

- Did you attempt to install more than once?
- if that is the case did you make sure to clean the database and `~/.config/pydio/cells` folder.
- What version of mysql are you using?

Hello,

There is a small bug in MySQL version v8.0.22 that is known and breaks the App.  
Where a still waiting for a bit to see if they fix it quickly in the .23 or if we have to implement a workaround (that is quite costly) on our side.  
Until then, please downgrade to the 8.0.21, thanks.
